posted on 2018-01-03, 21:19 authored by Hsing-Hua Hsieh, Fang-Chi Hsu, Yang-Fang ChenSelf-powered tactile sensing is the
upcoming technological orientation
for developing compact, robust, and energy-saving devices in human-machine
interfacing and electronic skin. Here, we report an intriguing type
of sensing device composed of a Pt crack-based sensor in series with
a polymer solar cell as a building block for energetically autonomous,
wearable, and tactile sensor. This coplanar device enables human activity
and physiological monitoring under indoor light illumination (2 mW/cm2) with acceptable and readible output signals. Additionally,
the device can also function as a photodetector and a thermometer
owing to the rapid response of the solar cell made from polymers.
Consequently, the proposed device is multifuntional, mechanically
robust, flexible, stretchable, and eco-friendly, which makes it suitable
for long-term medical healthcare and wearable technology as well as
environmental indication. Our designed green energy powered device
therefore opens up a new route of developing renewable energy based
portable and wearable systems.
